Int Forum Allergy Rhinol. Beta-2 transferrin is the most reliable confirmatory test for CSF leak. 2009 Jul. A possible cause of a delayed traumatic leak is a previously intact dural layer that has slowly herniated through a bony defect, finally tearing and allowing the cerebrospinal fluid (CSF) to leak. Fluid leaking from the nose or external auditory canal must first be positively identified as CSF. All material on this website is protected by copyright, Copyright 1994-2023 by WebMD LLC. Epub 2012 Aug 13. Rarely, the leak can originate in the middle or posterior cranial fossa and can reach the nasal cavity by way of the middle ear and eustachian tube. The cerebral ventricles may be reduced in size, and the pituitary gland may appear enlarged. In 1981, Wigand reported on the use of the endoscope to assist with the repair of a skull base defect. All methods of cisternographyradionuclide, CT, and MRprovide improved or optimal CSF fistula detection when the fistula is active and when a Valsalva maneuver or jugular venous compression is added to the imaging protocol.

Radiology. 134:110044. 2 However, the sign was not specific to CSF: mixtures of blood with saline, tears or rhinorrhea also produced halos; filter paper, paper towel, coffee filters and linen all Teachey W, Grayson J, Cho DY, Riley KO, Woodworth BA. The resulting communication with the central nervous system (CNS) can result in a multitude of infectious complications that impart significant morbidity and potentially disastrous long-term deficits for the patient. A study by Lieberman et al found evidence of a significant incidence of multiple simultaneous skull base defects in cases of spontaneous CSF rhinorrhea, reporting the existence of such defects in eight out of 44 patients (18.2%) in the study.

Eljamel MS, Pidgeon CN, Toland J, et al. Preoperative Medical Treatment for Patients With Acromegaly: Yes or No? The osteoplastic flap provides the surgeon with a view of the entire posterior table of the frontal sinus and is especially useful for defects more than 2 cm above the floor and lateral to the lamina papyracea. One drop of blood and one drop of either spinal fluid, saline, tap water, or rhinorrhea fluid were placed simultaneously on filter paper, and the specimens were examined after ten minutes for the development of a ring. Bonnie Kaplan, MD, showed a picture of blood leaking from the ear of an injured patient onto a bed sheet, which forms a double ring sign, in the December Quick Consult.

Higher-level studies are needed to better determine optimal diagnostic and clinical management approaches. Dandy is credited with the first surgical repair of a CSF leak via a frontal craniotomy approach in 1926. [QxMD MEDLINE Link]. The leakage stops within 1 week in 70% of patients, within 3 months in 20-30%, and within 6 months in most patients. AJNR Am J Neuroradiol. [QxMD MEDLINE Link]. From the third ventricle, the fluid circulates into the forth ventricle and out into the subarachnoid space via the foramina of Magendie and Luschka. Another technique, the injection of intrathecal fluorescein, has been used not only to diagnose CSF rhinorrhea but to localize the site(s) where it occurs. Therefore, it is important to keep in mind exactly what you said while also making sure a CSF leak and a basilar skull fracture are not missed. Traumatic CSF leak is reported in approximately 10-30% of skull base fractures in adults. [7], Brain and spinal MRI is useful in demonstrating meningocele and meningoencephalocele when associated with CSF leak, as well as for examining patients with spontaneous intracranial hypotension syndrome. The double ring ceremony was officiated by Monsignor David W . J Clin Diagn Res. The https:// ensures that you are connecting to the With one method, the average total time for coronal and sagittal imaging is 48 minutes. This occurred on bed linen, filter paper, absorbent paper, and coffee filters. Head images are acquired 2, 6, 12, and 24 hours after injection of the isotope. CSF leak; CSF rhinorrhea; cerebrospinal fluid; diagnosis; diagnostic algorithm; localization. 4:CD004884.

Magnetic resonance cisternography (MRC) should be used for CSF leak identification as a second line for each of these if beta-2 transferrin is not available or if HRCT is ambiguous. Typically, 0.5 mL of a 10% fluorescein solution is injected into the lumbar subarachnoid space over more than 1 minute. For more information, see Medscape. Sometimes, associated symptoms can assist in localizing the leak. This finding is suggestive of a site of cerebrospinal fluid leak. The gray scale is reversed for optimal viewing. [QxMD MEDLINE Link]. CSF leaks will often resolve within seven days with very few complications, and no clear evidence supports antibiotic prophylaxis for these leaks in the first seven days. PMC Defects in the posterior table of the frontal sinus may be approached externally via a coronal incision and osteoplastic flap. Disclaimer. Jinkins JR, Rudwan M, Krumina G, Tali ET.

Serum glucose, chloride, and total protein tests of the fluid are not specific or conclusive for CSF. An official website of the United States government. Fast CSF leaks have rapid contrast diffusion and may not be localized to a 2-vertebral segment of the spinal canal (suitable for local treatment by extradural blood patch or alternate therapy) by routine postmyelogram CT spine scan. However, if CSF rhinorrhea persists beyond this point, or if a large skull base defect is observed at the time of injury, surgical repair is warranted. J Neurosurg. 2nd edition. Extradural fluid collections are common in spinal CSF leak. High-resolution computed tomography (CT) scanning is the imaging modality of choice for identifying a skull base defect associated with CSF rhinorrhea. CSF will separate from blood when the mixture is placed on filter paper resulting in a central area of blood with an outer ring or halo. Dr. Kaplan responds: Thank you so much for your thoughtful reply to my article. [QxMD MEDLINE Link]. The type of filter paper did not affect the development of a ring. Clinical Radiology.

AJNR Am J Neuroradiol. Cerebrospinal fluid (CSF) leak may occur from the nose (rhinorrhea), from the external auditory canal (otorrhea), or from a traumatic or operative defect in the skull or spine. This site needs JavaScript to work properly. The patient's severe postural headaches were markedly decreased in intensity. CSF separates from blood when it is placed on filter paper, and it produces a clinically detectable sign: the ring sign, double-ring sign, or halo sign. [QxMD MEDLINE Link]. Epub 2018 Sep 24. FOIA Skull base injuries can vary from simple cracks in the bony architecture to large (>1 cm) defects with disruption of the dura and potentially brain parenchyma. This article discusses current concepts in the etiology, diagnosis, and treatment of CSF rhinorrhea, as well as long-term management of patients following successful treatment. [Full Text]. Cerebrospinal fluid imaging. Compared with external techniques, endoscopic techniques have several advantages, including better field visualization with enhanced illumination and magnified, as well as angled, visualization. CSF is produced at a rate of approximately 20 mL/h for a total of approximately 500 mL daily. Acute posttraumatic cerebrospinal fluid rhinorrhea. CSF consists of a mixture of water, electrolytes (Na+, K+, Mg2+, Ca2+, Cl-, and HCO3-), glucose (60-80% of blood glucose), amino acids, and various proteins (22-38 mg/dL). [8]. (EMN.

Conservative management consists of a 7-10 day trial of bed rest with the head of the bed elevated approximately 15-30. Axial fast spin-echo T2-weighted MRI demonstrates widened extra-axial fluid spaces but no focal extra-axial fluid collection. A 27-year-old male driver in a single-vehicle rollover collision was transferred to a trauma centre after stabilization and endotracheal intubation at a community hospital. [QxMD MEDLINE Link]. This terminology seems to imply that spontaneous CSF leaks are idiopathic in nature; however, recent evidence has led us to realize that spontaneous CSF rhinorrhea may in reality be secondary to an intracranial process, namely elevated intracranial pressure (ICP). DeConde AS, Suh JD, Ramakrishnan VR. [QxMD MEDLINE Link]. [28], In a small series of patients withspontaneous intracranial hypotension (SIH), instillation of preservative-free normal saline into the thecal sac followed by intrathecal Gd infusion was found to be a safe technique thatincreased the detection of a CSF leak on MR myelography images. Other sites of production include the ependymal surface layer (up to 30%) and capillary ultrafiltration (up to 20%). This site needs JavaScript to work properly. Neuroradiology. CMAJ. (See images below.). Intrathecal gadolinium-enhanced MR cisternography in the evaluation of clinically suspected cerebrospinal fluid rhinorrhea in humans: early experience.
